Possible reasons: Diet (any non-red meat eating diet for nutrient deficiencies, or too much meat due to reliance on fast food), drug/stimulant use (YOLO culture?), More sedentary lifestyle (Desk jobs, social media for 'entertainment'), Lack of resources to take time off from work (too many hours + high rents = no time/money to do have non-home hobbies)

The interesting statistic was the urban regions were less pronounced than the suburbs, which may indicate something either cultural or economic that may drive this change.

Either way, it's unfortunate. We're living in the best possible time in history, and many millennials are being impacted by something which - in some cases - may be completely avoidable.

"Energy drinks" (Red Bull, Monster, Rockstar et. al.) blew up in the late '90s/early 2000s or so. As far as I remember, early marketing for these was heavily targeted at "extreme sports" fans and practitioners of their less-extreme variants (e.g. skateboarding). I wonder if that targeting might have something to do with the urban/suburban split.

What does not consuming red-meat have to do with anything? Consumption of red meat is at an all time high and is growing every year.

I was curious to see if this was actually the case, but the data doesn't really seem to support this claim. Meat consumption overall appears to have remained relatively stable over the past few years, but it's mostly been an increase in poultry intake that's made up for a simultaneous decline in red meat consumption.

According to another comment here, iron deficiency is a common cause of strokes in younger people. Diets low in red meat often lead to iron deficiency. (Of course, this can be addressed with a supplement, but not everyone who avoids red meat also takes iron supplements.)

Excess iron in men also elevates cancer incidence, so I don't think one should take an iron supplement if there's no need. A blood test is necessary. If you look closely at the men and women's multivitamins that are sold in stores, you'll see that there is no iron on the men's multivits.

Excess iron can be reduced by donating blood.

Also important: cast iron cookware introduces a non-insignificant amount of iron into cooked food, which can be detrimental (or beneficial) depending on the subject.

High iron also correlates to an increased risk of heart disease, liver disease, diabetes, and more. http://www.webmd.com/men/features/too-much-iron-in-your-bloo... That's one reason why I donate blood regularly. They check my iron levels, then bleed off a bunch I don't need.
